Production costs = US$93 per ton of zinc ore.
Treatment Charges = Approx US$300 per ton of concentrate
Transportation costs = US$176 per ton of concentrate

Zinc concentrate = US$3,893,578,302
Mine Operating costs = US$585,900,000
Treatment Costs = $506,165,179
Transportation costs = US$303,350,943

Pre-Tax Profit = $2,498,162,179
